to switch the flow of grease into grease gun. Set it to the auto-
greasing side (A) when using the auto-greasing system, and
set it to the grease gun side (B) when using the grease gun.
Be sure to return this selector valve to the auto-greasing side
after using the grease gun.

REGULATOR
k k
WARNING
Do not increase the pressure of regulator up to 0.49 MPa or more {5 kg/cm
2
or more} . Since the pump
pressure ratio is 50:1, the pressure of grease increases up to 24.5 MPa {250 kg/cm
2
} . If it is used when
the pressure exceeds the specified value, this may cause a serious accident.
Regulator is used to adjust and stabilize the pressure of the
compressed air discharged from compressor to the appropriate
one.
The pressure of regulator is set at 0.44 MPa {4.5 kg/cm
2
} when
the machine is shipped from factory.
INJECTOR
The injector discharges the grease which is discharged from
the grease pump to each greasing point.
